Newbie exposure time question.

[Tony G]

 Hi all! I'm a solar guy but had a decent first round on Jupiter. Here's transit tonight!  What I have and my question.. 4" mak at 3800 fl. Zwo178. How long of a video before movement on a transite? If my software's set correct it's lo. And red spot near end. And I believe couple shadows.

120 seconds should be fine, maybe 150.

I normally do 150 secs for RGB and 180 secs for the L channel.  I think for you I would agree with the above comment of 120 secs, you could take multiple shorter images and derotate with Winjupos.
